FindGratingFunction
FindGratingFunction[system, options] is a function that determines the grating function between an object wavefront and reference wavefront hitting the last optical surface in the specified optical system.
As input, FindGratingFunction takes either an optical system containing two wavefronts or two light sources with one or more optical components. FindGratingFunction first calls FindWaveFronts to obtain the WaveVectorFunction for each light source hitting the last surface. FindGratingFunction assumes that first wavefront corresponds with the object wave and the second wavefront corresponds with the reference wave. FindGratingFunction then calculates the grating function by subtracting the object wave vector from the reference wave vector. FindGratingFunction works equally well for both point sources and planar sources. In addition, the light source need only contain a small number of rays (since the actual number of rays is internally specified).
If one-dimensional light sources are used (ie. WedgeOfRays or LineOfRays), then a one-dimensional grating function is calculated. If two-dimensional light sources are used (ie. PointOfRays or GridOfRays), then a two-dimensional grating function is determined.
See also: Hologram, Grating, FindWaveFronts, and OpticalPathDifference.

FindInterference
FindInterference[system, options] is a function that determines the interference function between multiple wavefronts hitting the last optical surface in an optical system.
As input, FindInterference takes either an optical system containing multiple light sources or the output from one or more FindWaveFronts calculations. FindInterference calculates the interference function by adding together the complex fields from the individual wavefronts hitting the optical surface and multiplying by the complex conjugate to get the intensity distribution on the surface. FindInterference works equally well for both point sources and planar sources. In addition, the light source need only contain a small number of rays (since the actual number of rays is internally specified).
If one-dimensional light sources are used (ie. WedgeOfRays or LineOfRays), then a one-dimensional interference function is calculated. If two-dimensional light sources are used (ie. PointOfRays or GridOfRays), then a two-dimensional interference function is determined. FindInterference is also a label used with the RenderedParameters option. See also: FindWaveFronts, InterferenceFunction, OpticalPathDifference, WaveFrontIntensity, and OpticalLengthFunction.

FindWaveFronts
FindWaveFronts[system, options] is a function designed to find the optical path length function and wave intensity function on a last surface in the optical system.
FindWaveFronts calculates the wavefront function and the intensity mapping function at the final surface. This information is used together by FindInterference to calculate the complex field as well as the interference at the surface. As input, FindWaveFronts uses an optical system containing one or more light sources. FindWaveFronts works equally well for both point sources and planar sources. In addition, the light source need only contain a small number of rays (since the actual number of rays is internally specified).
If a one-dimensional light source is used (ie. WedgeOfRays or LineOfRays), then one-dimensional wavefront and intensity functions are calculated. If a two-dimensional light source is used (ie. PointOfRays or GridOfRays), then two-dimensional wavefront and intensity functions are determined. FindWaveFronts is also a label used with the RenderedParameters option. See also: FindInterference, OpticalPathDifference, WaveFrontIntensity, and OpticalLengthFunction.
FocalFraction
FocalFraction is an option of FindLensParameters that specifies the focal point position relative to the paraxial and marginal focal points.
If FocalFraction -> 0 is given, the paraxial focal point position is used (determined by tracing paraxial rays through the system.) If FocalFraction -> 1 is given, the marginal focal point position is used (determined by the tracing outer marginal rays through the system.) If FocalFraction -> Automatic is given, the focal plane with the smallest overall spot size is chosen by tracing a filled source of rays ( also known as the circle of least confusion.) FocalFraction is normally used with FindImagePoint->True, however a user specified FocalFraction setting will over-ride the default FindImagePoint->False setting.

FrontFocalPoint is a rule that indicates the point of reverse focus in three-dimensions in the entrance of an imaging system.
GaussianPlot
GaussianPlot[opticalsystem, assumptions, options] is a function that propagates and plots one or more Gaussian beams through the optical system.
Note that one or more GaussianBeam sources must be present in the system before ShowGaussian can produce any results. GaussianPlot has two different plotting modes that are governed by the Plot3D option. For Plot3D->True, a full three-dimensional representation of the beam curvature together with the beam spot size (at 1/e of amplitude) are shown. For Plot3D->False, a paraxial depiction of the beam parameters indicated with the RenderedParameters option is presented in the form of two-dimensional plots. RenderedParameters takes a list containing one or more of the following values: BeamSpotSize, BeamCurvature, and ComplexBeamParameter. When Plot3D->True is invoked, then RenderedParameters->ComplexBeamParameter is not available. GaussianPlot internally calls GaussianTrace. GuassianPlot is also called internally by ShowSystem for the rendering of Gaussian beam information by Wavica.
See also: GaussianTrace, RenderedParameters, BeamCurvatureFunction, BeamCurvatureGraphics, BeamSpotSizeFunction, BeamSpotSizeGraphics, ComplexBeamParameterFunction, ComplexBeamParameterGraphics, and ShowGaussian.

See also OpticalLength.
GeometricPointSpreadFunction
GeometricPointSpreadFunction[system, options] calculates the intensity function at the focal plane of an imaging system.
GeometricPointSpreadFunction internally calls FindIntensity and can work directly with multiple wavelength (white light) incoherent sources, since it works only with the intensity information (not amplitude and phase). The optical system must contain a light source followed by the imaging optics with the approximate focal surface as its last element. For FindImagePoint->True, the last system element need not be the exact focal surface, since the exact focal surface position is automatically determined. When the default FindImagePoint->False is given, the last system element is assumed to be the exact focal surface. In addition, the light source need only contain a small number of rays (since the actual number of rays is internally specified). The user can also give as input a specific focal point or exit pupil position with the FocalPoint and ExitPupilPosition options, although GeometricPointSpreadFunction does not make use of the exit pupil information.
Note: GeometricPointSpreadFunction works equally well for both point sources and planar sources, as long as the described imaging system contains a focus. If a one-dimensional light source is used (ie. WedgeOfRays or LineOfRays), then a one-dimensional geometric point spread function is calculated. If a two-dimensional light source is used (ie. PointOfRays or GridOfRays), then the geometric point spread calculations are carried out in two-dimensions.
GeometricPointSpreadFunction does not utilize PupilFunction. GeometricPointSpreadFunction is also an option of OpticalTransferFunction and PointSpreadFunction that indicates whether the diffraction point spread function or the geometric point spread function is to be used. GeometricPointSpreadFunction->False invokes the direct use of PointSpreadFunction, while GeometricPointSpreadFunction->True invokes the use of GeometricPointSpreadFunction.
FindIntensity uses the KernelScale and SmoothKernelSize options to specify a Gaussian smoothing kernel that gets convolved with the intensity data. This smoothing kernel can be set to the diffraction-limited spot-size of the systen in order to incorporate the diffraction-limited behavior with the geometric ray-trace data.

For IntensityTransform->True, then PointSpreadFunction returns the real-valued intensity distribution of the point spread function and OpticalTransferFunction returns the intensity-based modulation and phase transfer functions. For IntensityTransform->False, then PointSpreadFunction returns the magnitude and phase field distribution of the amplitude point spread function and OpticalTransferFunction returns the complex-amplitude-based modulation and phase transfer functions.
IntensityTransform also affects the PaddingFactor->Automatic setting. PaddingFactor->Automatic uses a factor of zero for the amplitude transform (IntensityTransform->False) and a factor of one for the intensity transform (IntensityTransform->True).

OpticalTransferFunction
OpticalTransferFunction[system, options] calculates the modulation and phase transfer functions of the optical system for a given object source input.
OpticalTransferFunction works together with either GeometricPointSpreadFunction, FindIntensity, and PointSpreadFunction. OpticalTransferFunction first calls either GeometricPointSpreadFunction or PointSpreadFunction to find the point spread function of the imaging system. Finally, OpticalTransferFunction calculates a modulation and phase transfer function by using the Fourier transform of the point spread function. As input, OpticalTransferFunction takes either an optical system or the returned output from either GeometricPointSpreadFunction, FindIntensity, or PointSpreadFunction. The optical system must contain a light source followed by the imaging optics with the approximate focal surface as its last element. For FindImagePoint->True, the last system element need not be the exact focal surface, since the exact focal surface position is automatically determined. When the default FindImagePoint->False is given, the last system element is assumed to be the exact focal surface. In addition, the light source need only contain a small number of rays (since the actual number of rays is internally specified). When FindPupils->False is used, the optical surface preceding the image surface is taken as the field stop. The user can also give as input a specific focal point or exit pupil position with the FocalPoint and ExitPupilPosition options.
Note: OpticalTransferFunction works equally well for both point sources and planar sources, as long as the described imaging system contains a focus. If a one-dimensional light source is used (ie. WedgeOfRays or LineOfRays), then a one-dimensional modulation transfer function is calculated. If a two-dimensional light source is used (ie. PointOfRays or GridOfRays), then the optical transfer function calculations are carried out in two-dimensions. Warning: in general, most one-dimensional and two-dimensional results are not fully equivalent to each other.
OpticalTransferFunction is also a label used with the RenderedParameters option. See also: IntensityTransform, FindLensParameters, PupilFunction, PointSpreadFunction, ModulationTransferFunction, PhaseTransferFunction, OTF, MTF, FindIntensity, and GeometricPointSpreadFunction.

PointSpreadFunction first calls PupilFunction to calculate the exit pupil function. Finally, PointSpreadFunction calculates a point spread function by using the Fourier transform of the calculated complex field. As input, PointSpreadFunction takes either an optical system or the returned output from PupilFunction. The optical system must contain a light source followed by the imaging optics with the approximate focal surface as its last element. For FindImagePoint->True, the last system element need not be the exact focal surface, since the exact focal surface position is automatically determined. When the default FindImagePoint->False is given, the last system element is assumed to be the exact focal surface. In addition, the light source need only contain a small number of rays (since the actual number of rays is internally specified). When FindPupils->False is used, the optical surface preceding the image surface is taken as the field stop. The user can also give as input a specific focal point or exit pupil position with the FocalPoint and ExitPupilPosition options.
Note: PointSpreadFunction works equally well for both point sources and planar sources, as long as the described imaging system contains a focus. If a one-dimensional light source is used (ie. WedgeOfRays or LineOfRays), then a one-dimensional point spread function is calculated. If a two-dimensional light source is used (ie. PointOfRays or GridOfRays), then the point spread calculations are carried out in two-dimensions. Warning: in general, one-dimensional and two-dimensional results are not fully equivalent to each other.
PointSpreadFunction is also a label used with the RenderedParameters option. PointSpreadFunction is also the name of a returned rule from PointSpreadFunction that gives the point spread function result for a specific image point.

PupilFunction
PupilFunction[system, options] is a function designed to find and extract the optical path difference and intensity profile on a spherical surface at the exit pupil of an imaging system.
PupilFunction first calls FindLensParameters to characterize the system. Then, PupilFunction calculates a wavefront function and the intensity mapping function at the exit pupil. This information can be used together to calculate the complex field at the exit pupil. As input, PupilFunction takes either an optical system or the returned output from FindLensParameters. The optical system must contain a light source followed by the imaging optics with the approximate focal surface as its last element. For FindImagePoint->True, the last system element need not be the exact focal surface, since the exact focal surface position is automatically determined. When the default FindImagePoint->False is given, the last system element is assumed to be the exact focal surface. In addition, the light source need only contain a small number of rays (since the actual number of rays is internally specified). PupilFunction uses information from FindLensParameters about the field stop position. When FindPupils->False is used, the optical surface preceding the image surface is taken as the field stop. The user can also give as input a specific focal point or exit pupil position with the FocalPoint and ExitPupilPosition options.
Note: PupilFunction works equally well for both point sources and planar sources, as long as the described imaging system contains a focus. If a one-dimensional light source is used (ie. WedgeOfRays or LineOfRays), then a one-dimensional pupil function is calculated. If a two-dimensional light source is used (ie. PointOfRays or GridOfRays), then the two-dimensional pupil function is determined.

The SignalPlotCutoff threshold is defined as the ratio of the minimum signal to the peak signal. Note that SignalPlotCutoff does not change the actual point spread function data output, which is left uneffected. SignalPlotCutoff is also used to calculate the DiffractionSpotSize value. For SignalPlotCutoff->False, the plot domain is the entire data set and DiffractionSpotSize measures the half-maximum signal level.

See also: LensABCDMatrix.
TaylorSeries
TaylorSeries[f, {x, x0, n}] generates a power series expansion for f about the point x = x0 to order (x - x0)^n. TaylorSeries[f, {x, x0, nx}, {y, y0, ny}] successively finds series expansions with respect to y, then x. TaylorSeries performs the same mathematical operations as the built-in Series function of Mathematica, but overcomes some apparent difficulties with Mathematica's built-in Series function.
In particular, in some cases, the built-in Series function appears to freeze Mathematica under varying conditions. However in cases with very large calculations, the new TaylorSeries function may perform much more slowly than the built-in Series function. Therefore, in order to handle these varying conditions, TaylorSeries is also an option name of the TaylorSeries function that indicates which internal algorythm is used by TaylorSeries. TaylorSeries->(TaylorSeries or True) always uses the TaylorSeries algorythm. TaylorSeries->Automatic switches to the built-in Series function for order terms larger than 2. TaylorSeries->(Series or False) uses the internal Series function at all times.

See also: AngularMagnification and SystemABCDMatrix.
WaveFrontIntensity
WaveFrontIntensity is a returned rule that gives a continuous intensity function at a designated surface.
WaveFrontIntensity is also a label used with the RenderedParameters option.
Wavica
Wavica is an extension of Wavica for wave propagation-related activities. This version 1.0 has the build-date Dec 14, 2004.
See also: Needs, $SystemSymbolsInWavica.
WavicaPrivate
WavicaPrivate[switch] put the Wavica private context on the $ContextPath (switch equals True) or remove it (switch equals False). See also: SwitchContextPath.
WavicaSymbols
WavicaSymbols[string] returns a list of names defined in Wavica that are related to the given parameter string. It is fixed at the ending of the loading process and derived from ListedSymbolNames.
ZernikeFit
ZernikeFit[{{coordinatepoint, opticalpathlength},...}, options] is a utility function that attempts to find a Zernike polynomial equation fit to the wavefront data as given by a list of two-dimensional coordinates and optical path length values (in wavelength units).
ZernikeFit->True is also a option that indicates the use of a Zernike polynomial equation fit to a wavefront. ZernikeFit->False usually indicates the use of an Interpolation function instead.
See also: ZernikePolynomial, ZernikeOrder, SeidelAberrations, and ResidualFitError.
ZernikeOrder
ZernikeOrder is a option to ZernikeFit that indicates the maximum series order to be fitted in the Zernike polynomial series.
See also: ZernikeFit, ZernikePolynomial, SeidelAberrations, and ResidualFitError.
ZernikePolynomial
ZernikePolynomial is a rule returned by ZernikeFit that gives the Zernike polynomial equation fit to a optical path data (in wavelength units).
See also: ZernikeFit, ZernikeOrder, SeidelAberrations, and ResidualFitError.
$SimplifyByteConstraint
$SimplifyByteConstraint is an global variable used internally by SymbolicTrace to limit the ByteCount size of expressions. Initially, $SimplifyByteConstraint is set to be equal to the MaxByteCount option setting. In the event that a Simplify evaluation of an expression exceeds its TimeConstraint, the value of $SimplifyByteConstraint is reset to the offending expression's ByteCount multiplied by a factor of 0.75.
$SimplifyID
$SimplifyID is an global variable used internally by SymbolicTrace to track specific Simplify call events. The value of $SimplifyID is automatically incremented with every new internal call to a Simplify or FullSimplify function and is used in the SkipSimplify option to skip particular simplify operations.
$SystemSymbolsInWavica
$SystemSymbolsInWavica is a list of symbols in the System context, used specially or modified in Wavica.
